There is actually room for 4 filters.
I've often seen the advice that beginners should "for one year use one camera, one lens, and one film". While not exactly a beginner I intend to try this anyway in the hope to become a better photographer. I will use my Pentax LX, my 43/1.9 limited and lots of Delta 3200. I often shoot in low light situations.
I have a small case attached to the camera strap with room for three filters. Which three filters would you recommend that I should always bring with me, and why?
Many thanks in advance!
For the filter on the lens;
a B+W KR 1.5 MRC, in an F-Pro mount.
For the case;
1. A Polarizing filter.
Next depending on what you're shooting
2. Either a yellow K2, #8 filter, or
a yellow - green X0, #11 filter.
The #8, is better for landscapes, the #11 is better for people.
3. Either a Lt Red #23, or a Med Red #25 filter.
The #23 is better for people ( of color ), the #25 is better for landscapes.
The filter factors for these filters are as follows:

Carry 4 filters. A UV on your lens for protection
For a third filter I always liked taking along a slight warming filter for shooting in shade
The B+W KR 1.5 filter loses only 0.1 of a stop, but acts like a 1/3 of a stop loss 81 filter.
Thus combining the best of Alan Gales 1st & 3rd filters !
Polarizers vary anywhere from 1 stop, 2.5 stops.
The #8 Yellow's filter factor is 1 stop.
The #11 Yellow - Green's filter factor is 1.5 stops.
The #23 Lt Red's filter factor is 2.5 stops.
The #25 Med Red's filter factor is 3 stops.
I hope that this will help you make your choice.
